Secure remote subscription management
First Claim
1. A method for use in wireless communication by a wireless transmit/receive unit (WTRU), the method comprising:
- the WTRU establishing a connection to an initial connectivity operator (ICO) using a first keyset and an initial connectivity operator identifier;
the WTRU receiving, from the ICO, a first subscriber identifier associated with a selected home operator;
the WTRU generating, after receiving the first subscriber identifier from the ICO, a second keyset using a keyset generation protocol, wherein the second keyset is different from the first keyset;
the WTRU using the second keyset and the first subscriber identifier to establish a connection to the selected home operator; and
,wherein the ICO is informed that the second keyset has been generated.

Abstract
A method and apparatus are disclosed for performing secure remote subscription management. Secure remote subscription management may include providing the Wireless Transmit/Receive Unit (WTRU) with a connectivity identifier, such as a Provisional Connectivity Identifier (PCID), which may be used to establish an initial network connection to an Initial Connectivity Operator (ICO) for initial secure remote registration, provisioning, and activation. A connection to the ICO may be used to remotely provision the WTRU with credentials associated with the Selected Home Operator (SHO). A credential, such as a cryptographic keyset, which may be included in the Trusted Physical Unit (TPU), may be allocated to the SHO and may be activated. The WTRU may establish a network connection to the SHO and may receive services using the remotely managed credentials. Secure remote subscription management may be repeated to associate the WTRU with another SHO.

8. A method for use in wireless communication by a wireless transmit/receive unit (WTRU), the method comprising:
-
the WTRU establishing a connection to an initial connectivity operator (ICO) using a first keyset and an initial connectivity operator identifier, the first keyset and the initial connectivity operator identifier being provisioned on the WTRU; the WTRU receiving a first subscriber identifier from the ICO, the first subscriber identifier being associated with a first selected home operator; the WTRU generating, after receiving the first subscriber identifier, a second keyset using a keyset generation protocol, wherein the second keyset is different from the first keyset; the WTRU establishing a connection to the first selected home operator using the second keyset and the first subscriber identifier; the WTRU thereafter receiving a second subscriber identifier, the second subscriber identifier being associated with a second selected home operator; the WTRU generating, after receiving the second subscriber identifier, a third keyset different from the second keyset using the keyset generation protocol; the WTRU establishing a connection to the second selected home operator using the second subscriber identifier and the third keyset; and
,wherein the ICO is informed that the second keyset and the third keyset have been generated. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
